SPECIFICATION forming part of Letters .Patent No. 610,715, datedSeptember 13, 1898.

Application filed March 10, 1898. Serial No. 673,321. (No model.)

To all whom it may concern:

Be it known that we, AMOS E. LONG and ALBERT A. JONES, of the city ofPhiladelphia, in the State of Pennsylvania, have invented certain newand useful Improvements in Caps for Bottles, Jars, &c., of which thefollowing is 'a specification, reference being had to the accompanyingdrawings.

O'ur invention relates to closures for vessels designed to be used butonce and is adapted to indicate by its condition whether the vessel uponwhich it is secured has been opened or not.

Generally stated, our invention comprises a cap, preferably of sheetmetal, provided with resilient sheet-metal tongues, the latter beingadapted to automatically engage beneath a flange or lip upon the vesselto which the cap is applied in such manner as not to be detachabletherefrom except by mutilation of the latter.

In the accompanying drawings,'Figure 1 is a sectional view showing aconvenient embodiment of our invention applied upon a bottle. Fig. 2 isa sectional view showing a modified form of our invention applied upon ajar. Fig. 3 is a side elevation of the form of our invention shown inFig. 1'. Fig. 4 is a fragmentary sectional view of theform of ourinvention shown in Fig. 2.

Referring to Fig. 1, A is the bottle, the neck A of which is providedwith a lateral flange or lip A and B is the cork inserted in said neck.The cap 0, which is adapted to in close said cork and neck, is providedwith resilient sheet-metal tongues 0, adapted to automatically engagebeneath the flange or lip A when the cap is placed in position, asindicated in Fig. 1.

The neck A is preferably provided with a shoulder a, projecting beneaththe cap 0 and preferably of a diameter equal thereto, the shoulder aprojecting beneath the cap 0 for engagement with the lower edge thereofand said tongues 0 being seated in the recess A In the form of ourinvention shown in Fig. 2 the jar A is provided with a rigid cork or stoer B which ma be maintained in air- PD a tight relation with the formerby means of the intermediate packing-ring b preferably of soft rubber.In the latter form the resilient tongues o of the cap O engage beneaththe flange a in the manner above set forth. It is obvious that it isnecessary to destroy the cap O in order to remove the stopper B As shownin the several figures, the metal tongues which serve to secure the capin position upon the vessel-neck are in integral relation with thecap-body and may be conveniently formed as illustrated in Fig. 4, beingstruck up from the dotted position to the position shown in full linestherein. 7

We are aware that it is not broadly new to form avessel-closure of sheetmetal. We believe it to be broadly new, however, to combine with such acap as we have described means to effect its automatic engagement andprevent its removal, as herein set forth.

Although we have shown our invention as applied upon bottles and jars,we do not desire to limit ourselves to such embodiments thereof.Moreover, it is obvious that various modifications may be made withoutdeparting from the spirit of our invention. We therefore do not desireto limit ourselves to the precise construction which we have shown anddescribed.

We claim In a vessel-closure of the class described, the combinationwith a vessel-neck, having a continuous recess A and provided with anupper and a lower annular shoulder, of a cap provided at its continuouslower edge with integral struck-up and inwardly-bent tongues, the freeextremities of which engage said upper annular shoulder, and theopposite extremities and lower edge of which engage said lower annularshoulder, substantially as set forth.
